Repeater Loopback

The Repeater Loopback (RLB) loops data received from the data ports and the

DSX-1 interface after the signal has passed through the framing circuitry. Use

RLB to ensure that all of the data is correct up to the point where it is sent over

the interface. This helps to indicate that the FrameSaver unit is operational.

An attached device or test equipment should generate and monitor data to be

looped back.

The T1 NAM will not respond to any messages from the network during this test.

CAUTION:

This test may affect the operation of the frame relay PVCs assigned to

the selected port. While in loopback, the frame relay link will be down

so any IP data being sent while this test is active will be disrupted.

An RLB cannot be started when one of the following tests is active:

HPayload Loopback, Send Remote Line Loopback, or an active Monitor

Pattern on this network interface.

HAll loopbacks on the DSX-1 interface.

HSend FT1 Loopback or Data Channel Loopback on the synchronous

data port.
